Attaching hyperpolarised diamonds to molecules targeting cancers the technique can allow tracking ofthe molecules’ movement in the body

Researchers have found a way to use diamonds to act as beacons in magnetic

resonance imaging (MRI) scans and identify cancerous tumours before they become

life-threatening.

Their findings revealed how a synthetic version of the precious gem can light up

early-stage cancers in MRI scans. “We knew nano diamonds were of interest for

delivering drugs during chemotherapy because they are largely non-toxic and non-

reactive,” said David Reilly from University of Sydney in Australia.

“We thought we could build on these non-toxic properties realising that diamonds

have magnetic characteristics enabling them to act as beacons in MRIs,” Reilly

noted.

The researchers turned their attention to hyperpolarising nano-diamonds, a

process of aligning atoms inside a diamond so they create a signal detectable by an

MRI scanner. “By attaching hyperpolarised diamonds to molecules targeting

cancers the technique can allow tracking of the molecules’ movement in the body,”

the study’s lead author Ewa Rej from University of Sydney noted.

“This is a great example of how quantum physics research tackles real-world

problems, in this case opening the way for us to image and target cancers long

before they become life-threatening,” Reilly said. The study was published in the

journal Nature Communications.

A very expensive way to probe cancer indeed! And, who will pay for it when it inflictspeople with little or no resources? Cancer diagnostic or treatment busters. May be the authors science is OK (not novel as people have used other moleculeswith different kind of reporters!) but will not gain tracktion.
